Increase in the slope of the rising edge of the Al L2,3 X-ray fluorescence spectrum for the G1-3 grating in the first order (left), G1-3 in the second diffraction order (middle) and G1-4 in the first diffraction order (right) upon approach of the CCD position to 125 mm. The red line is the fit of the parabolic function to the data. |
